SHUTTLE-CARRIER MECHANISIVI FOR NET-MAKING MACI-IINES.

Application file December 14, 1912.

To all 207mm it 77m7/ concc'm:

Be it known that l, Pn'rnn Konn'r, a subject of the King of Prussia,residing1 at the city of Hamburg, in the State of l-lamburg, GermanEmpire, have invented certain new and useful luiprovements inShuttle-Carrier Mechanism for Net-MakingMachines, of which the followingis a specification.

This invention has for its object to produce an improved shuttle-carrierniech anism for net-making machines of the Jonannin type whereby themovements of the shuttle-czirrier and the parts coperating therewith areshortencd and modified in such a inanner as to improve considerably theworking' of the machine and siinplify its construction.

in existing` net-making' machines the shuttle-carrier usually movesto-and-fro only along a horizontal and coinparatively long path, andconsequently those machines can be driven only at a comparatively slowspeed, and yet it has been found impossible to work such machineswithout Vihration. Now according to tie present invention the to-and-fromovement of the Slnittle-carrier is shortened by more than half, and italso receives a partial rotation for the purposeof bring-in;` the pointsof the shuttlcs to the gi'ippers. By this means the further advantage isattained that con'ipared with existing i'nachines the grippcrs also needonly make a. considerably shorter moveinent for the Purpose ofdelivering the gripped thread to the points of the shuttles. Theseimprovemcnts have the effect of rendcringl the working of the machinesteadier and more uniform, and of enahling the machine to be driven at aeonsiderahly higher speed. Further the complicated motiontransmittingdevices (such as elliptic Wheels and the like) employed with the objectof prcventing' Vibration and shock, may be dispenscd with because theimproved mode of Operating1 the machine rcnders the lattcr practicallyfree from ribration.

Une manner of carrying out this inventiqn is illnstrated by way ofexaingle in the.. acconipanying)` drawings in which :-fl

Figura l shows the parts in the positions they occupy at the l'ioginningof the movement of the shuttle. Fi 2 shows the parts in their positio`when. the npper threads ,are being drawn in; Fi 3 shows the parts intheir positions when the upper loops are specification of Letters atent.

being delivcrcd by the grippers to the shuttles.

'l`he carriage a for the rotary Shuttle-carrier receives a shortto-and-fro movenient from the connecting rod c. The Shuttlecarrier Z) isconnected to a toothed sector d which adapted to roll over a rack e inthe longitudinal inovemcnt of the carriage a, and thereby cause theshuttle-carrier Z) with the Shuttle f to rotate. The gripper holder f/is caused by any suitable means to move horizontally in such a manner asto bring the cripped thread to the point of the shuttle. ln the examplethe gripper holder is shown suspended in a pendulating nianner. Thecoinb h has the usual movements.

The accompanyino; drawings illustrate the several. positions of theearriage a and shuttlc f. As the carriage o moves back, the point of theshuttle is gradually rotated upward in such a manner as to he broughtnearer to the grippers, so that the latter need make only acorrespondingly reduced movement.

Any suitable means may bo employed instead of the rack and Sector gear.

I claim:

1. In a net making machine, the combination of a. main frame, of acarriage reciprocal in a straight line on the frame, a Shuttle carrierniounted on said carriage, shuttle carricr Operating means including arack and segment, and means connected to the carriz'ig'e fori'eciprocating` same and elfectino' operation of the shuttle carrieroperating' means.

2. ln a net making` machine, the combination with the main frame, of acarriage movably inounted thereon, means for Operating said n'iovablecarriag'e, a Shuttle carrier inounted on said carriage, a 'ack bar onsaid frame, and means between the Shuttle carrier and the rack baradapted to operate the Shuttle carrier, said means comprising a toothedsector engaging said rack bar and fastened to said shnttle carrier,Whereby a n'iovement of the movable carriage will operate the shuttlecarrier.

l'n testiinony whercof I aliix my signature in presence of twowitnesses.
